Recognize the danger

Recognize the Danger:

A major cause of confined space injuries/fatalities is the failure to recognize the incident for what it is….

A CONFINED SPACE INCIDENT !


Always keep in mind
Always keep in mind

  • The Survival Profile of Victim !!!!!

  • According to statistic we are going after victims not patients

  • Provision for non-entry rescue

  • Every C.S. incident will be investigated by OSHA.

  • Entry into a C.S. is mission specific


Osha will be looking for
OSHA will be looking for…

  • The C.S. to determine if it meets the requirements for a Permit Required Confined Space (p.r.s.c.)

  • Two permits

  • Training records (authorized)

  • Provision(s) for non-entry rescue


3 most common osha citations issued in calif
3 Most Common OSHA Citations issued in Calif.

  • Failure to provide hazard(s) communication to rescuers

  • Failure to provide appropriate equipment

  • Failure to provide training on equipment


Regulations
Regulations

  • AB 111 = negligent supervisor

  • AB 1127 “The Big One” Jan. 2000

  • Title 8 CCR GISO 5156, 5157 & 5158


Assembly bill 111

Assembly Bill 111

One of the first regulatory laws enacted to hold C.S. entrants accountable.


Ab 1127

AB 1127 “$$”

Enacted in January 2000. Says we show up, allow something to happen, somebody gets injured/killed, we share responsibility.

Is Prosecuted as a Felony!!


Title 8 ccr 5156
Title 8 CCR, 5156…

Grants an exclusion to

  • Construction operations

  • Agricultural operations

  • Marine terminal operations

  • Shipyard operations

  • Telecommunications manholes/Vaults

  • Grain handling facilities

  • Natural gas distribution

  • Electrical utility operations underground vaults


Title 8 ccr 5157
Title 8 CCR, 5157…

  • Specific requirements on how to enter a Permit Required Confined Space.

  • Applies to Rescue Companies

  • Lists the mandatory components

  • Includes appendices that may be enforceable by OSHA


Title 8 ccr 5158
Title 8 CCR, 5158…

  • Lists requirements for those 8 industries that are exempted under 5156(b) (2)


A confined space is
A Confined Space is…

  • An area large enough and so configured that an employee can bodily enter to perform assigned work and:

  • Has limited or restricted means for entry/egress and;

  • Is not designed for continuous employee occupancy


Types of confined spaces
Types of Confined Spaces

  • Sewers

  • Railroads Cars

  • Vaults and pits

  • Vessels, silos, storage bins

  • Hoppers, pipelines


Reason for entering a confined space
Reason for Entering A Confined Space

  • Cleaning

  • Inspections

  • Maintenance

  • Training

  • Rescue


A permit required confined space
A Permit Required Confined Space…

  • Contains or has the potential to contain a hazardous atmosphere or,

  • Contains a material that has the potential for engulfing an entrant or,

  • Has an internal configuration such that an entrant could become trapped or asphyxiated by inwardly converging walls or by a floor which slopes downward and tapers to a smaller cross-section or,

  • Contains any other recognized serious safety or health hazard


Silos industrial or agricultural

Silos -Industrial or Agricultural


Manholes sanitary or storm
Manholes- Sanitary or Storm


What are the hazards to rescuers at c s incidents
What are the Hazards to Rescuers at C.S. incidents?

  • Atmosphere 65%

  • Engulfment 13%

    Bridging

  • Physical 7%

  • Corrosive

  • Biological

  • Psychological


Osha says these are mandatory positions
OSHA Says these are Mandatory Positions

  • Entry Supervisor

  • Attendant

  • Entrant

  • Back-up entrant


What is an entry
What is an Entry?

The action by which a person passes through an opening into a permit required confined space, and includes ensuing work activities in that space

Considered to have occurred as soon as any part of the entrants body breaks the plane of an opening into the space


Mandatory components for a c s entry
Mandatory Components for a C.S. entry

  • Written Policy (including Permit)

  • Lock out/Tag out

  • Provide rescue/standby

  • Atmospheric monitoring

  • Communications

  • Ventilation (unless it increases hazard)

  • Retrieval Line (provision for non-entry rescue)

  • Appropriate harness

  • Mechanical Advantage if > 5’ fall


Confined space and metro fire

Lock Out/Tag Out is….

  • Isolation

  • Purging

  • Inerting

  • Ventilation

  • Barricades

  • Lock out/tag out


Lock out tag out kit
Lock-Out/Tag-Out Kit

  • Padlocks

  • Hasps & tags

  • Plug & valve covers

  • Chain

  • Electrical Tester


Reasons for monitoring
Reasons for Monitoring

  • Assess the survival profile of the victim

  • Atmospheres are the #1 killer of C.S. occupants


Hazardous atmospheres
Hazardous Atmospheres

  • Oxygen levels below 19.5% or above 23.5%

  • Atmosphere at or above 10% of the LEL

  • Airborne combustible dusts which reduce vision to 5’ or less

  • Atmosphere with products/vapors at or above their IDLH levels.


What are we monitoring for
What are we monitoring for ?

  • Oxygen

  • Flammable/Explosive atmospheres

  • Selected toxics

    Usually CO & H2S


Oxygen

Oxygen

-Recorded as a %

-OSHA says 19.5% - 23.5% is

acceptable entry range

-Oxygen is always checked first


Flammable or explosive atmospheres

Flammable or Explosive atmospheres

Usually recorded as % LEL. ppm or % gas

10% of the LEL is the upper limit for entry

Difference between LEL 100% & vapor 100%


Hydrogen sulfide h2s

Hydrogen Sulfide H2S

Colorless, odor of rotten eggs

Destroys olfactory senses

Ppm, 10 ppm entry limit


Carbon monoxide co

Carbon Monoxide (CO)

Colorless, odorless, explosive

ppm

25 ppm is limit for entry


How we monitor
How we monitor

  • Prior to entry (approach monitoring)

  • Continuously during entry

  • At 4’ intervals

  • DOCUMENT


Communications
Communications

  • 5157 states mandatory between Attendant & Entrant

  • Radio

  • Hardwired

  • Rope signals O.A.T.H.


Ventilation
Ventilation

  • Increases survivability profile

    - reduces LEL’s to safe levels

    - temperature conducive for human

    habitation

  • Replaces contaminated air

    Air exchanges

  • Reduces explosion chances


Retrieval system
Retrieval System

The equipment including a retrieval line, class III harness, wristlets, if appropriate, (and lifting device) used for non-entry rescue of workers from a permit-required confined space


Mechanical advantage
Mechanical Advantage

  • Required for vertical C.S. more than 5’ deep

  • Hand operated, approved winch w/ cable

  • Rope and pulleys with brake

  • Not considered the retrieval line


Types of respiratory protection
Types of Respiratory Protection

  • APR - Air Purifying Respirator

  • SCBA – Self Contained Breathing Apparatus

  • SAR - Supplied Air Respirator


Recognize exposure to yourself co workers
Recognize exposure to yourself & co-workers

  • Headache

  • Dizziness

  • Nausea

  • Smell or rotten eggs

  • Euphoria
